Definitions
- the invention relates to a locating device for land vehicles according to the preamble of the main claim.
- Examples include references to kindergartens, schools, homes for the elderly and the blind, gradients, construction sites, underpasses, curves and the like. In most cases, the failure to perceive such information remains without harmful consequences Unfortunate chaining of several circumstances, the missing information can make a decisive contribution to an accident event.
- the locating device has the advantage that additional information can also be evaluated in computer-aided locating systems.
- This additional information like the data for the electronic road map, is stored in a memory and, depending on the location of the vehicle, is stored with the Road information correlated so that it is available at the appropriate time. Additional roadside transmitters are therefore not required.
- the stored safety-relevant information can also include information that is essential for those unfamiliar with the area, but is not considered to be worth mentioning by traffic signs by the responsible traffic authorities.
- the driver can be asked to shift into a lower gear or, if the temperature is very low, the driver can be warned of bends against black ice.
- the signal is output in such a timely manner that the driver can adjust to the situation in good time.
- it is advisable to output the information in a direction-specific manner, so that, for example, the driver can already recognize that critical situations can only occur if he turns right, for example, but not when driving straight ahead.
- the signal is used to control appropriate manipulated variables for controlling vehicle units.
- the throttle valve position can be changed if the speed is too high, or a gear change can be initiated automatically in the case of an automatic transmission if there is a danger to the driver and the vehicle.
- it is also advantageous to suppress or request preselectable types of information in particular to suppress information if the driver is already informed about most dangerous situations by driving on these routes more often, or if the driver wants to know in advance which information is required Dangers he has to reckon with on a certain route.
- Fig. 1 shows an information output system which obtains safety-relevant information by correlation with data from an electronic road map and outputs it optically and acoustically
- Fig. 2 shows an information output system like Fig. 1, but additionally with sensors, an input terminal and actuators.
- the information output system shown in Fig. 1 is essentially limited to the basic idea of the invention. It includes an additional memory 12 in which safety-relevant information of certain sections of the route is stored.
- a positioning and navigation system for land vehicles 14, known per se, with a corresponding memory 10 for geographic data of an electronic road map are provided as further components.
- a correlation circuit 16, which is followed by an input-output circuit 18, is used to evaluate both stored data.
- the input-output circuit 18 is followed by an output unit 20, which comprises an LCD display 24 for graphic symbols and characters as well as a car radio 26 known per se in connection with a speech synthesizer and a loudspeaker 28.
- the road network data which was previously determined empirically by test vehicles, is stored in the form of an electronic, digitized road map. The driver then enters his start and destination position via an input terminal. During the journey, location data are obtained via wheel sensors, from which the current vehicle position is determined via the length and the direction. By comparing this data with the stored data, the driver is then given information about the direction of travel.
- Safety-related information is located in the additional memory 12. This can be the same information that should be conveyed to the driver by physical danger signs on the roadside. Furthermore, such information can also be stored that is not contained on traffic signs, but is useful to increase traffic safety for drivers unfamiliar with the location. In addition, the information can also be coupled with recommendations, for example not to exceed a certain speed, to switch on a certain gear selection range, to switch lights on or off, to operate the turn signal or on particularly dangerous roads. or traffic constellations.
- this additionally stored safety-relevant information is correlated with the current location data of the location and navigation system 14. If the driver reaches a section of the path to which corresponding safety-relevant information is stored, this information is passed on by the correlation circuit 16 to the output unit 20 via the input-output circuit 18.
- the traffic sign is shown as a symbol on the LCD display 24 or is announced in plain text via the car radio 26 provided with the speech synthesizer and a recommendation is given. In the case of a curve, this could e.g. read: "Attention right turn, maximum speed 80 km per hour.”
- the information assigned to this section of the route is often only relevant for one direction of travel.
- the corresponding information is then expediently output in a direction-specific manner only for the relevant direction of travel.
- the information output system can be supplemented accordingly in accordance with the exemplary embodiment described above.
- the output signal of the correlation circuit arrives 16 via a converter circuit 36, a comparator 34 and an evaluation circuit 22 for the input-output circuit 18.
- the comparator 34 and the evaluation circuit 22 are connected to sensors 30 and an input terminal 32 via control or signal lines.
- the output unit 20 additionally includes actuators 38 which act on vehicle units.
- preselectable information can be requested or suppressed. For example, locations of petrol stations, kiosks, police, pharmacies, post offices, banks can also be saved. If the driver would like to be made aware of a corresponding device on the way between his exit position and his target position, he can select this via the input display 32. When he reaches the corresponding section of the route, he is then made aware of the selected facility in good time so that he can search for a corresponding drive or a parking space and can alert the following traffic to his intention to stop or turn. Conversely, black ice or skidding warnings can be suppressed, if such weather conditions can rule out such dangers and the corresponding warnings would be perceived as disturbing.
- driving and environmental data can also be recorded automatically. This is done via the sensors 30.
- the sensors can be displacement and speed sensors, sensors of the gear selection range, the vehicle weight or the outside temperature.
- information about the vehicle height, the vehicle length or the trailer operation can expediently be entered via the input terminal 32.
- comparator 34 determines whether the current speed is above or below the recommended directional speed. If it is far below the target speed, a message will expediently be omitted; if it is above the target speed, however, the driver will be informed of the curve and the recommended target speed.
- warning information is output or not can also be made on downhill sections. Attributes such as trailer operation or high weight can be taken into account, which would possibly lead to less braking deceleration.
- the outside temperature could also be determined by means of temperature sensors and a criterion could be found as to whether or not an indication of a risk of black ice is issued.
- a criterion could be found as to whether or not an indication of a risk of black ice is issued.
- restrictions also apply when driving over bridges or underpasses. By adding the information output system, the driver can, if necessary, be made aware of an insufficient load of a bridge or an insufficient passage height of an underpass.
- the safety-relevant information can also be used to control actuators 38 that actuate vehicle assemblies.
- this influencing must be carried out with the appropriate caution, so that dangerous situations are not created which should be avoided by the influencing itself.
- An influence caused by an actuator could e.g. switching on the light when entering tunnels or underpasses, switching down an automatic gearbox to a lower range of choice on downhill gradients or reducing the speed stopped by a speed limit.
- the brake could also be actuated if the circumstances indicate that the driver is getting into an otherwise uncontrollable dangerous situation.
- Such information can be transmitted only once to the actuators 38 for executing actuating commands, but it is advisable to provide additional transmission for an optical or acoustic output.
